'Innovative' and 'active' are the key words in this interview question. Hiring managers would like to see that you are vocal and actively contribute your ideas and experience to a project. If possible think of an example where you may have initiated or took charge of a project. It will be important to emphasize your role in coming up with the innovative solution to the problem and to not spend too much time explaining the problem itself.

"While working for one of my previous employers, I was engaged in an initiative aimed at identifying the cause of the company's high employee turnover rate. By examining data from other areas of the company including Marketing, Finance and Operations, I identified key areas that required further examination. I found the data in these areas of the company had some high correlations with employee turnover rates. I worked with the analysts in these departments to better understand these correlations. This led to strategic changes within these departments that had a positive effect on the employee turnover rate."
